Publication number: 20050090371Abstract: In an internal combustion engine for a vehicle having a drive clutch, a blowby control system includes a fresh air introducing channel, for introducing fresh air into a crankcase, and a blowby gas return channel for returning blowby gas from the crankcase to an air-intake system. A blowby control valve is provided in the fresh air introducing channel or the blowby gas return channel, for selectively restricting gas flow through the blowby system. A controller is also provided on the vehicle for controlling operation of the blowby control valve. The controller is programmed to switch the blowby control valve from the closed state to the open state, with the drive clutch connected, when the vehicle starts traveling. The blowby control system and method hereof can reduce variations in the engine speed occurring during engine idling and before clutch engagement, to improve ride quality of the vehicle.Type: ApplicationFiled: September 24, 2004Publication date: April 28, 2005Applicant: Honda Motor Co., Ltd.Inventors: Hiroyuki Nakajima, Yuuki Muraoka, Nobuhiro Shimada, Ryuji Moriyama

Publication number: 20040172519Abstract: A processor has an instruction set A and an instruction set B. A system instruction decoder decodes a system instruction that specifies the operating mode of the processor, the system instruction not being included in either the instruction set A or the instruction set B. A system instruction execution controller receives a decoded signal from the system instruction decoder, which has decoded an instruction requiring changeover of the instruction set, and sets the value of a instruction mode register. On the basis of the value in the instruction mode register, an instruction set changeover unit selects the instruction set to be used.Type: ApplicationFiled: February 24, 2004Publication date: September 2, 2004Applicant: NEC Electronics CorporationInventor: Hiroyuki Nakajima

Patent number: 6719933Abstract: A method of making a spherical seamless capsule formed by encapsulating a filler material such as a medicine with a capsule shell material shell such as gelatin. A liquid capsule shell material is stored in a tank at a low temperature, and supplied to a concentric multiple nozzle while it temperature is raised to a predetermined temperature upon being gradually heated while being transferred to the concentric multiple nozzle. This prevents deterioration in the capsule shell material and excessive decrease in its viscosity. When the liquid filler material and the capsule shell material flow out of the concentric multiple nozzle, their flows are cut by imparting a vibration thereto, to form a droplet in which the filler material and the capsule shell material are disposed at the center and on the outside, respectively. Such droplets are dropped into a curing liquid while in a dispersed state to cure the surface of the capsule shell material.Type: GrantFiled: September 25, 2002Date of Patent: April 13, 2004Assignee: Chugai Seiyaku Kabushiki KaishaInventors: Takeshi Nakamura, Kaoru Nemoto, Isao Matsuda, Hiroyuki Nakajima

Patent number: 6627094Abstract: The method of the present invention is capable of manufacturing a thin film head, which includes a protection layer having enough corrosion-resisting property and water-repellent property, which is capable of keeping the magnetic head clean even if temperature and humidity are high, and which has enough durability and reliability. The method of manufacturing the thin film head, in which a pad, which contacts a disk, and a floating pattern are formed in a disk-side face, comprises the steps of: forming a adhesion layer on the disk-side face of a substrate, which is a main body of the thin film head; forming a protection layer on the adhesion layer; coating the protection layer with resist; patterning the resist so as to form a pad hole at a prescribed position, at which the pad is formed; forming a pad film on resist-coated faces including an inner face of the pad hole; and lifting off the resist so as to form the pad.Type: GrantFiled: November 30, 2000Date of Patent: September 30, 2003Assignee: Fujitsu LimitedInventors: Motoichi Watanuki, Hiroyuki Nakajima

Publication number: 20030180485Abstract: Disclosed is a method of manufacturing a spherical seamless capsule formed by encapsulating a filler material such as a medicine with a capsule shell material such as gelatin. A concentric multiple nozzle is positioned above the liquid surface of a curing liquid such that the tip of the nozzle faces down. A concentric columnar composite flow which is discharged from this concentric multiple nozzle and which is composed of a filler material and a capsule shell material outside the filler material is immersed in the curing liquid, and cut in the curing liquid to form a droplet. The capsule shell material of the droplet is cured by the curing liquid, and thereby a seamless capsule is formed. Since, the droplet is not dropped into the curing liquid, no deformation of the droplet caused by collision against the liquid surface occurs. The tip of the multiple nozzle is positioned above the liquid surface of the curing liquid.Type: ApplicationFiled: February 14, 2003Publication date: September 25, 2003Inventors: Hiroyuki Nakajima, Masayoshi Yamazaki, Takeshi Nakamura, Tsukasa Yamamoto

Publication number: 20020172625Abstract: A catalytic apparatus for exhaust purification, provided in an exhaust path of an internal-combustion engine operable with at least a theoretical air-fuel ratio and a lean air-fuel ratio, is provided with a three-way catalyst (4) having an inner layer (12a) thereof mainly containing rhodium as a noble metal to be activated in an oxygen concentration lowering atmosphere and a surface layer (12b) thereof mainly containing platinum or palladium as a noble metal to be activated in an oxygen concentration increasing atmosphere. In the catalytic apparatus, platinum or palladium in the surface layer is activated in lean operation to perform an HC purifying function effectively. If oxygen is temporarily in short supply during the change from a lean air-fuel ratio of exhaust gas over to a stoichiometric air-fuel ratio, oxygen is supplemented to purify HC by utilizing the O2 storage function of platinum or palladium as the noble metal, whereby the HC purifying rate can be prevented from temporarily suddenly lowering.Type: ApplicationFiled: July 8, 2002Publication date: November 21, 2002Inventors: Hiroyuki Nakajima, Hirokuni Seto, Keisuke Tashiro, Osamu Nakayama, Shigeyoshi Taniguchi, Hideki Gotoh

Patent number: 6218804Abstract: An engine stopping/starting control unit having improved accelerating performance. A charging limiting device is provided which limits the charge provided to a generator when the vehicle is stopped. The decreased charging allows for better performance when the vehicle accelerates from a stopped states. Also, the vehicle headlight can be dimmed while the vehicle is stopped, which reduces the load on the generator. An acceleration detector detects when the vehicle accelerates during running, and can decrease the generator load in response to the acceleration.Type: GrantFiled: December 28, 1999Date of Patent: April 17, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masayuki Toriyama, Tomokazu Sakamoto, Satoshi Honda, Toru Iwadate, Masahide Yokoo, Hiroyuki Nakajima, Takeshi Yanagisawa

Patent number: 5808186Abstract: A method for detecting a misfire by fluctuation in crankshaft rotation in which the occurrence of a misfire can be detected exactly by eliminating the effect of detection error in detecting the fluctuation in crankshaft rotation, caused by the error in the construction of a crank angle sensor. By succeedingly receiving pulses from the crank angle sensor, a processor detects a time interval taken from the entering into a crankshaft rotation angle region, relating to a cylinder corresponding to both pulses, to the leaving therefrom (S2), calculates the crankshaft angular acceleration D.omega..sub.n by using the correction factor calculated on the basis of the above detected time interval, and the time interval determined by dividing the time taken for one rotation of the crankshaft by the number of cylinders (S3, S4), the latter interval being free from sensor error, and detects the occurrence of a misfire when the calculated value D.omega..sub.n is less than the decision value (S5 through S7).Type: GrantFiled: February 2, 1994Date of Patent: September 15, 1998Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Takuya Matsumoto, Toru Hashimoto, Mitsuhiro Miyake, Yasuhisa Yoshida, Mitsuhiko Yanagisawa, Hiroyuki Nakajima, Koichi Namiki, Satoshi Kasai
